Based on the classification of patent citations within the same firm as the reuse of actualized technologies and one of buried technologies, this paper exploratory examined the conditions which facilitate technology reuse. The results implied that actualized technologies were not so incremental. Also, from an exploratory analysis
to find the factors for valuing the reused technologies, the author confirmed some differences with the results between the case of actualized technology and one of buried technology, however, the same inventors on citing
and cited patents had no significant contribution to these values.
